description

The present invention relates to an apparatus and a method for palletizing stucco compositions.

Palletizers are known in the art. In this case, an empty pallet is initially provided in a loading station for loading a pallet and then placed in layers, such as bottle crates, disposable containers or the like. Usually, interlayers are arranged, for example, made of paper or cardboard between individual bundle layers.

From DE 29 45 883 Al a device for loading pallets with piece goods is known. This device has transverse to a Lagenüberschubrichtung running Abstutzschienen in which a Unterstutzungsebene is guided.

From G 92 02 553.6 a device for dispensing and forming Stuckgutstapeln is known. This device has a plurality of vacuum grippers, which grip the Stuckguter itself from above. Below this vacuum gripper, a support plane in the form of a roller carpet is provided, which can be moved under the stucco position. In addition, terminal strips are provided to clamp the Stuckgutlagen.

Furthermore, it is known from the prior art that such palletizing in each case in succession an intermediate layer, then arrange a container layer and then again an intermediate layer to each other. However, this method is relatively time consuming.

The present invention is therefore based on the object to provide a palletizer available, which allows a higher Palletiergeschwindigkeit. This is inventively achieved by devices according to claim 1 and 14 and a method according to claim 15. advantageous

Embodiments and further developments are the subject of the dependent claims.

An inventive device for forming stacks of stucco compositions has a movable transport device for transporting the Stuckgutzzusammenstellungen. In addition, a support device is provided, which can be moved under the stucco assembly and which can be removed substantially completely from a region below the stucco assembly.

According to the invention, the transport device has at least one controllable fixing device for temporarily fixing an intermediate layer, wherein this fixing device is movable below the support device for fixing the intermediate layer.

Thus, it is proposed according to the invention that the transport device for the stucco assemblies or the bundle layers is combined with a fixing device for the intermediate layer to be arranged between the bundle layers. In this way, a stack can be formed faster with the help of only one device. The Stuckgutzzusammenstellungen is, as mentioned above, the palettierenden layers of containers. For palletizing, for example, with the aid of the device according to the invention, first of all an intermediate layer can be deposited and then, without loss of time, above the clipboard, a stucco assembly. This process can then be repeated. Thus, a significant acceleration over previously known methods can be achieved and there are advantageously no additional movement devices for inserting the intermediate layers necessary.

The supply device preferably leads the piece goods assembly of the transport device transversely, ie the piece piece assembly is guided substantially in a horizontal direction. The transport device preferably has a lateral opening, through which the stucco assembly can be pushed into the transport device. Moving below the piece of fabric composition is understood to mean that the fixing device can be moved to a position which is lower than the piece piece composition. It is also conceivable that the Fixing device within a range that is below the Stuckgutzzusammenstellung is moved.

A fixing device is understood to mean a device which is capable of holding an intermediate layer at least temporarily on the transport device.

Preferably, the fixing device is integrated into the support device such that its movement is coupled to the movement of the support device. For the method according to the invention, it is thus possible first to deposit a clipboard and then to remove the supporting device together with the fixing device from the area underneath the piece piece assembly. Preferably, the fixing device for carrying out the fixing operation is arranged in a region which lies below the support device, so that the intermediate layer can be held below the piece of plaster.

In a further advantageous embodiment, the support device on a plurality of rotatable bodies, which opposite the Stuckgutzzusammenstellung is abstutzbar. As mentioned above, it is necessary in one process step to move the support device relative to the stucco assembly. In order to prevent that by this process, for example, packaging enclosing films are torn, the mentioned freely rotatable bodies are provided, which allow a rolling against the Stuckgutzzusammenstellung.

In a further advantageous embodiment, the support device in the plane of a bottom surface of the

Stuckgutzusammenstellung against the Stuckgutzzusammenstellung movable. More specifically, it is possible to move the support device like a curtain against the Stuckgutzzusammenstellung. For this purpose, the rotatable bodies or these rotatable body bearing waves or axles are guided in two-sided rails.

In a further advantageous embodiment, the fixing device has at least one fixing element, which is arranged between two rotatable bodies. More specifically, the fixing elements are integrated in the curtain formed of a plurality of rotatable bodies. In a further advantageous embodiment, the fixing device has a strip-shaped body, which is movable in two lateral rails together with the rotatable bodies. This means that such a strip-shaped body can be arranged, for example, between two rotatable bodies and thus can be displaced together with these rotatable bodies in relation to the piece of fabric.

In a further advantageous embodiment, at least one fixing element is a controllable suction head. It is thus proposed to mount at least one such suction head in the support device, which is preferably designed as a blind carpet. In addition, however, it would also be possible to attach a fixing device, for example in the form of a clamping device below the support device. A controllable suction head is understood to mean that the fixing operation can be controlled by the user or by a machine control, so that optionally an intermediate layer to be lifted can be picked up and released.

In a further preferred embodiment, the fixing device has two spaced-apart strip-shaped bodies, at least one fixing element being arranged on each of these strip-shaped bodies, and a plurality of rotatable bodies being provided between these two strip-shaped bodies.

Each of these strip-shaped bodies also preferably has at least two such fixing elements. In this way, a plurality of such fixing elements can be distributed substantially uniformly over the largest possible area of the intermediate layers in a particularly advantageous manner, so that a particularly efficient hold of the intermediate layers is possible.

In a further advantageous embodiment, the support device has two mutually substantially symmetrically formed sections. To open the bottom of the transport device, these two sections slide apart and release in this way the area below the Stuckgutzzusammenstellung. In a further advantageous embodiment, the

Transport device arranged in its entirety on an arm pivotable about a vertical axis. In this way, the

Transport device Grab piece assemblies and place them in another place, for example on a pallet.

In a further advantageous embodiment, the device has a pre-processing unit, which leads the intermediate layers to an underside of the support device. In this way it is achieved that the transport device, without having to be moved over long distances, both the Stuckgutzusammestellung and the intermediate layer can accommodate, making short cycle times are achievable.

In a further preferred embodiment, the transport device has a coupling device, which is in an operating state in fluid communication with the fixing device and which is separated in a further operating state of the fixing device of this. More precisely, this coupling device serves to provide a vacuum to the fixing elements designed as suction heads on the support device. In a closed state of the support device or of the roller carpet, the coupling device docks onto the suction strips of the support device and then this can be subjected to a vacuum.

This coupling device is preferably also used to temporarily apply compressed air to the suction head, in order to solve in this way the respective intermediate layer of the suction head. Preferably, the coupling device is designed to be pivotable and can be created by this pivoting action on the strips or pulled away from them.

The present invention is further directed to a transporting device for transporting the piece of goods, comprising a support which is movable under the piece of fabric and which is substantially completely removable from a region located vertically below the piece of fabric.

According to the invention, the transport device has at least one controllable fixing device for temporary fixing of an intermediate layer, wherein this fixing device for fixing the intermediate layer is movable below the Stuckgutzusammenstellung and wherein the fixing device is integrated into the support device such that their movement and the movement of the support device is coupled.

The present invention is further directed to a method of forming stacks of stucco compositions. In this case, the Stuckgutzzusammenstellung is introduced into a transport device in a process step, the Stuckgutzusammenstellung is moved relative to a support device of the transport device and moved to this support device. In a further method step, the transport device is transported, wherein during transport the stucco assembly is trimmed by the support device.

According to the invention, an intermediate layer is at least temporarily taken up by the transport device by means of a fixing device arranged on the transport device and preferably on the support device.

Thus, in the method according to the invention, both the stucco assembly itself and the intermediate layer are gripped by the same transport device, so that a time saving is also possible here.

Preferably, the transport device itself with the

Stuckgutzzusammenstellung and moved with the intermediate layer by a lifting movement and possibly also by a pivoting movement to store the intermediate layer and the Stuckgutzzusammenstellung example, on a pallet.

In a preferred method, the fixing device is moved together with the support device with respect to the stucco assembly. Thus, the fixing device is coupled to the support device so that in this way the entire movement process can be simplified.

Fig. 8 is a detail view of a fixing device.

1 shows an inventive device 1 for forming stacks of Stuckgutzzusammenstellungen 10. In this case, the reference numeral 4 refers to a shifter, which is part of a supply device 5 and which pushes the Stuckgutzzusammenstellungen 10 in a transport device 2 into it. In addition, intermediate layers 13 are brought from below to this transport device 2.

The transport device 2 is preferably rotatably arranged on an arm 7. This arm 7 is in turn arranged on a central rotatable frame 8. In this way, the recorded Stuckgutzzusammenstellungen 10 can be required together with an intermediate layer 13 on a pallet. Another corresponding arm 7, on which a further transport device 2 is provided, can be seen in a rudimentary manner on the right side in FIG. FIG. 2 shows a further view of the device 1 shown in FIG. 1. In addition, a reservoir 11 (shown only diagrammatically) for intermediate layers 13 can also be seen here.

It can be seen that the stucco sets 10 are inserted from the side into the transport device 2. For this purpose, the transport device 2 has a lateral opening 2a. The transport device 2 itself is brought from above to the intermediate layers 13.

FIG. 3 shows a further illustration of a device 1 according to the invention. It can be seen here that the intermediate layers 13 are temporarily deposited on a table 14 before they are gripped by a transport device 2. This table 14 can be changed by means of controlled betatigbarer cylinder 16 in its height in order to move an intermediate position from below to the transport device 2.

FIG. 4 shows a transport device 2 according to the invention. This has two side parts 15, between which a support device 6 is arranged. This support device 6 has a plurality of rotatable bodies 12. For transport is a

Stuckgückzusammenstellung or packaged layer laterally in the direction of arrow P pushed into the transport device 2 and during this process, the rotatable body 12, which are rollers, rotated. After the Stuckgutzzusammenstellung is pushed into the transport device 2, the transport device can transport the Stuckgutzzusammenstellung.

Furthermore, a displaceable rod 28 is provided, which can align the Stuckgutzzusammenstellung in the interior of the transport device 2 in the direction of the arrow Pl. For this purpose, the rod 28 can move in a rail along the arrow Pl. As the stock package is inserted, the bar 28 is moved up to the top to avoid hampering imports of the stock package.

Reference numeral 26 refers to a shaft arranged between the two side parts 15. This shaft is powered by a motor 24 and a gear 25 is rotated. By means of this shaft 26 and two arranged on her gears 27 (only one gear is visible), the support means 6 can be moved over an open chain and thus free the area below the Stuckgutzzusammenstellung. A corresponding shaft 26 is also provided on the rear side of the transport device 2 in FIG.

About a carrier 18, the transport device 2 can be arranged on a pivot arm. The apparatus further comprises a rail in which the support means 6 can be displaced to open the area closed by the support means 6 in FIG. The reference numeral 34 refers to the above-mentioned coupling devices to provide the flachformigen body or suction bars 20 with vacuum. In this case, these coupling devices 34 are designed so that they apply a vacuum on the suction strips only in the closed state of the support shown in Figure 1.

After the Stuckgutzusammenstellung was inserted into the transport device 2 or even before, in the closed state shown in Figure 1 via the coupling means 34, the suction bars 20 are activated to suck a arranged below the conveyor 2 intermediate layer or record and then this intermediate layer together with the To transport pieces 2. Through this common transport a significant cost and time savings is achieved.

FIG. 5 shows a plan view from below of a transport device 2 according to the invention. It can be seen that four strip-shaped bodies or suction bars 20 are integrated into the supporting device 6 here. In this case, these strip-shaped bodies 20 are each arranged between rotatable bodies 12. Preferably, the strip-shaped bodies 20 are arranged in relation to the rotatable body in such a way that, upwardly, the strip-shaped body 20 does not come into contact with the pieces of stucco. In the embodiment shown in FIG. 2, the support device 6 is composed of two sub-sections 6a and 6b which are formed substantially symmetrically with respect to one another.

In order to deposit the stucco assembly at its destination, the two sections 6a, 6b are pulled apart, so that between the Both sections 6a, 6b, an opening 9 is released, through which the Stuckgutzzusammenstellung can fall down. In the embodiment shown in FIG. 2, a total of four strip-shaped bodies 20 are provided, on which in turn a multiplicity of fixing elements or suction elements 22 is provided. By the arrangement shown in Figure 2, a very gleichmaßige distribution of these suction heads 22 over the entire surface of the transport device 2 is achieved.

Thus, it is possible to suck the liners during loading of the louver head (i.e., the conveyor 2) by the conveyor 2 directly under the loading surface. When placing the Stuckgückusammenstellung on the pallet can thus be stored by approaching only one position, the intermediate layer and the package layer.

The reference numeral 34 also shows a coupling device to pressurize the strip-shaped body 20 and thus also the individual suction elements 22 with vacuum. The reference numeral 23 refers to sensor devices which detect the presence of intermediate layers. These may be, for example, touch sensors or light sensors.

FIG. 6 shows a side view of a transport device 2 according to the invention. Stroke bodies 36, which serve as transport securing, in order to avoid damage, in particular, of the coupling devices 34, can also be seen here. After this has taken place, the intermediate layers are sucked in by the suction elements shown in FIG. The reference numeral 40 refers to a vacuum distribution device, which applies vacuum to the individual strip-shaped bodies 20 shown in FIG. In addition, compressed air can also be output to the coupling devices 34 and thus the suction elements 22 via this vacuum distribution device 40.

FIG. 7 shows a further side view of a transport device according to the invention. A further displacement device 38, which serves for the lateral alignment of the container assembly, can be seen here in particular. This further displacement device 38 is arranged on a carrier 39. Another (not shown) Displacement device is provided on the opposite side of the transport device 2.

The reference numeral 28 refers back to the rod, which prevents falling out of the container from the transport device 2.

FIG. 8 illustrates the supply of the vacuum to the strip-shaped bodies (not shown) from FIG. 2. In this case, a total of four coupling devices are provided, which act on the strip-shaped bodies 20 with the vacuum. These coupling devices 34 are arranged in the embodiment shown in FIG. 5 on a common carrier 41. This carrier 41 in turn is arranged via connecting devices 54 on the side parts 15 of the transport device shown in Figure 1. The coupling devices 34 have coupling heads 42, which are pivotable downwards.

For this purpose, these coupling heads 42 are arranged on a Auslegearm 44, which in turn is pivotally mounted relative to a carrier 46. The reference numeral 48 refers to a connection with which, for example via a hose, the coupling head 42 can be subjected to vacuum. Also, compressed air can be supplied via this hose.

The reference numeral 40 also shows the vacuum distribution device, which is not arranged at the position shown in FIG. 8, but preferably below the carrier 41. This vacuum distribution device 40 has a multiplicity of outlets 52, to which the above-mentioned hoses for supplying the individual coupling heads 42 may be connected. By applying the coupling heads 42 with vacuum, as mentioned above, an intermediate layer can be tightened. To lower the intermediate layer, this vacuum is removed and preferably additional compressed air is output. Subsequently, the support device 6 can be moved relative to the coupling heads 42. This makes it possible, the coupling heads 42 and the entire coupling device 34 stationary and thus less susceptible to wear. The reference numeral 56 refers to a filter, which is a Venturiduse 58 downstream. The vacuum distribution device 40 is supplied with compressed air via a connection 60. All disclosed in the application documents features are claimed as essential to the invention, provided they are new individually or in combination over the prior art.

Instead of rotatable rollers or rollers, the support device 6 of the transport device 2 can be formed from non-rotatable strips, rods or slats. It is also conceivable a split plate, the halves of which can be stored apart or moved together controlled.
